Message:

reconf: when a local router in a cluster is faulty, the cores are kept
deactivated.

  • In the physical implementation this is achieved with the hardware reset signal. This signal is masked with the GO signals of the NoC BIST. Only when all the local routers pass the BIST, the reset signal of the cores is deasserted.
